d-sub standard connectors wholesale are widely used in many fields as key components for connecting electronic devices. Regarding its main classification and composition materials, it can be summarized as follows:

1, the main classification of d-sub standard connectors wholesale:

d-sub standard connectors wholesale can be divided into a variety of types according to different classification standards:

1. Classification by appearance:

▪ Circular connector: With a circular insert surface, suitable for a variety of standard and non-standard applications.

▪ Rectangular connectors: Having a rectangular or trapezoidal insert surface, usually used for connection of a specific device or system.

2. Classification by purpose and use:

▪ Mobile phone connectors, power connectors, high voltage connectors, automotive connectors, aviation connectors, high-speed signal connectors and optical fiber connectors. These connectors are designed according to specific application scenarios and requirements.

3. Classified according to the termination form of the contact:

▪ Types such as crimp, weld, wrap and TAB, which determine the connection between the connector and the cable or device.

4. Categorize by fixed way:

▪ Fixed connectors and free end connectors, depending on how the connector is installed and used.

5. According to the plug and socket connection type:

▪ Snap, in-line, snap, thread and automatic connection types, which provide different connection tightness and convenience.

6. Classification by special environment and needs:

▪ Explosion-proof, high temperature resistance, radiation resistance, etc., these types of connectors can maintain stable connection performance in extreme environments.

7. By material:

d-sub standard connectors wholesale: Connectors are metal materials with strong corrosion and high temperature resistance, suitable for use in extreme environments.

▪ Plastic d-sub standard connectors wholesale: Engineering plastics as raw materials, mainly used in mild environmental aviation equipment.

Two: d-sub standard connectors wholesale components:

d-sub standard connectors wholesale components mainly include the following aspects:

1. Metal materials:

Metal materials are commonly used in the manufacture of connectors, housings and other parts in d-sub standard connectors wholesale, and are popular for their high strength and corrosion resistance. Common metal materials include copper, aluminum, stainless steel and so on.

2. Plastic material:

▪ Plastic materials are widely used in the manufacture of d-sub standard connectors wholesale because of their lightweight and durable properties. Common plastic materials include PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), nylon and so on. These materials have good mechanical properties, heat resistance and insulation.

3. Composite materials:

Composite materials combine the advantages of a variety of materials, such as high strength, high toughness, etc., so it is also used in d-sub standard connectors wholesale. Common composite materials include glass fiber reinforced plastics, carbon fiber composite materials and so on.

4. Insulation material:

▪ Insulation plays a vital role in d-sub standard connectors wholesale to isolate current and protect circuits. Common insulating materials include thermosetting plastics (such as phenolic resin, epoxy resin) and thermoplastics (such as glass fiber reinforced PET, PBT, etc.). In addition, there are some new insulating materials such as modified PPS, new LCP, etc., which have better processing properties and heat resistance.

To sum up, the classification of d-sub standard connectors wholesale is diverse and complex to meet the needs of different application scenarios. At the same time, its composition materials also cover metal, plastic, composite materials and insulation materials and other aspects to ensure that the performance of the connector is stable and reliable.
